Ciphering not provided operator insecure transmission'' How can i fix this please. I have sony erricson K850i Thanks


Ciphering is mainly caused due to old sim cards,remove your sim and reinsert it.If the problem still persists,go to the customer care center of the operator and ask for new sim with the same number ,you would probably get this for free .Insert the new sim and see to it that the problem is gone now

Insert correct usim on a sony ericsson w595.


You need to purchase a network unlock code from '3'. This will enable you to put any sim in the handset.
Local markets somtimes do a phone unlock service too.
